Description

UNITED STATES PATENT OFFICE.
CHARLES OLANTON KEYSER, OF NEWPORT NEWS, VIRGINIA.
SPROCKET-WHEEL.
SPEGIFIGATION forming part of Letters Patent No. 720,442, dated February 10, 1903.
Application filed October 15, 1902- Serial No. 127,375- (No model.)
T0 at whom it may concern.-
Be it known that 1, CHARLES CLANTON KEY- SER, a citizen of the United'States, and a resident of Newport News, in the county of Warwick and State of Virginia, have invented new and useful Improvements in Sprocket- Wheels, of which the following is a full, clear, and exact description.
This invention relates to improvements in sprocket-wheels particularly adapted for use in connection with motor-bicycles or motorvehicles; and the object is to provide a sprocket-wheel of simple construction and having spring-yielding parts, whereby the jarring or vibration is avoided while riding, starting, or stopping.
I will describe a sprocket-wheel embodying my invention and then point out the novel features in the appended claims.
Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in both the figures.
Figure 1 is a sideclevation of a sprocketwheel embodying my invention, and Fig. 2 is a section on the line x a; in Fig. 1.
The sprocket-wheel comprises an inner ring 1, designed to be connected to the hub of the rear wheel, and an outer ring 2, connected to the inner ring 1 by means of arms 3. Mounted to move on the outer ring 2 is a toothed ring 4, having inwardly-extended lugs 5,
which pass into the spaces between the arms 3 and at the opposite sides thereof, as clearly shown in Fig. 1. A ring 6 passes loosely through openings in the lugs 5 and is clamped to the arms 3 by means of the clips or plates 7, and surrounding this ring between thelugs 5 and the arms 3 are, springs v8 9. By this arrangement upon starting the motor the outer ring or toothed member will have a slight spring-yielding-like motion, thus preventing a jar or shock and preventing the jerky motion so disagreeable in riding motor-cycles, 86c.
The periphery of the ring 2 is provided with a raceway l0, and the inner periphery of the member 4: is provided with an annular raceway 11, and in the raceways bearing-balls 12 are placed. These bearing-balls may be inserted through an opening 13 formed'in the side of the member 4. The ring 2 is provided at one end with a flange 14, which engages against the side of the member 4, and in this flange is formed a channel to receive a packing-ring 15, of feltor similar material. The flange portion 16 of the toothed member is also provided at its inner side with an annular channel, in which is placed a packingring 17, of felt or like material. These packing-rings will prevent the entrance of dirt or dust to the raceways and ball-bearings.
Having thus described my invention, I claim as new and desire to secure by Letters Patent- 1. A sprocket-wheel, comprising an inner ring and an outer ring, arms connecting the two rings, a toothed member mounted to move on the outer ring and having perforated lugs, a ring extended through the said lugs and clamped to the said arms, springs surrounding the ring and engaging with the said lugs and arms, and bearing-balls between the outer ring and the toothed member.
2. A sprocket-Wheel comprising an inner ring and an outer ring, arms connecting the two rings, a toothed member mounted to move on the outer ring and having perforated lugs, a ring extended through said lugs and clamped to said arms, and springs surrounding the ring and engaging with said lugs and arms.
3. A sprocket-wheel comprising an inner ring and an outer ring, arm connections between said rings, a toothed member mounted to move on the outer ring and having inwardly-extended perforated lugs, a ring passing loosely through said lugs and clamped to the arms, springs arranged between the lugs and arms and packing-rings arranged between the said outer ring and the toothed member.
In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
CHARLES OLANTON KEYSER.
